Chemi-pure can be used with all water types as a chemical absorption filter and ion generator and exchange unit to positively keep pH at a perfect constant level. Also fantastic for use with African Cichlids and Discus! Needs replacement only every six months under normal circumstances. Use 1 unit up to 40 gallons, 2 units from 40 to 100 gallons, above 100 gallons add one unit for every 25 gals. 10oz.

Soft corals - Crustose Coralline Algaes - Caulerpas - Gorgonias - Seafans - other invertebrates and fish of all species thrive and grow luxuriously with no water change necessary using real seawater or the better imported mixes. This is not a claim, but fact, experienced by thousands of CHEMI-PURE users. In fact, salt water fish have spawned repeatedly in 5 year old water. CHEMI-PURE does not remove trace elements and is the only filter medium which aids in the natural balance of positive and negative charges, with an emphasis on the beneficial negative ion. CHEMI-PURE comes packed in pure polyester filter bags in sealed plastic bottles, called 1 unit, one of which is recommended for up to 40 gallons of water, and which is completely active for 4-6 months with no `regeneration` or cleaning required and is cheaper than carbon or pads. The one filtration product we unreservedly recommend for use with CHEMI-PURE is the Poly-Filter, by Poly-Bio Marine! Use one pad above and one below the CHEMI-PURE bag. We also recommend the use of foam fractionation or "protein skimmers."

Manufacturer Info

Boyd Enterprises Aquarium SuppliesBoyd Enterprises was founded in 1962 by Dick Boyd, who had been working in aquarium stores since 1947 at the age of 17. He had a love and passion for building and maintaining aquariums as a hobby. Through his constant experimentation to create his own filtration techniques, he developed the world renowned Chemi-pure - the original ion filter medium. In 1955, Dick Boyd along with three others founded the first Marine Aquarium Society in the United States. In 1972, he and his wife Linda, moved into a house large enough so he could build his dream aquarium. It took two years, but by 1974 Mr. Boyd had constructed a 3,000 gallon aquarium that was home to various corals, fish and invertebrates. Boyd Enterprises strives to keep up Dick’s level of Excellence, quality and customer service.

I've been using this product for years and it keeps the water clear. I only have to change the filter about every 6 months in my 70 gallon freshwater tank.

Excellent

I use the 10 oz Chemipure in my JBJ 24 gallon Nano Cube. Works great! It does a very good job of reducing nitrates and also does a great job of keeping my water crystal clear. Doesn't cost much and is well worth it in my opinion.

excellent

I have been a customer for a few years and get quick response to any questions that I may have about a product. I recently asked them about the chemi-pure & chemi-Pure elite product and was informed about the difference. I have seven tanks most with canister and one with sump and use the chemi-pure product in all of them. When it comes to maintaining your tank filter system I don't think you can get a better product. I put one chemi-Pure & one chemi-Pure elite in each one of my canister filters, the sump alot of each and it keeps my water clear much longer than your basic carbon. Thanks, for the large bulk discount and to chemi-Pure for such a quality product. Craig Berthelot

It works!

I'm not sure just how the ion exchange works with this unit but it does exactly what it says it will do! I've been using it for almost 3 years now and my nitrates are 0! I have a dozen fish in a 180 and have not done a water change in a year and that was only after a 5 day power outage. Thanks Chemi-Pure! You save me hours and hours of work.
